This page for the 2003 Toyota 4Runner helps you verify bulb sizes by lighting position, so you can match the correct replacement before you buy. Whether you are changing a headlight, interior lamp, or rear signal bulb, the chart is organized to make fitment checks faster and easier.
The 2003 4Runner uses different bulb types depending on the lamp location, and some positions may vary by trim, market, or lighting package. Use the bulb list on this page to confirm the right size for high beams, brake lights, reverse lights, dome lights, license plate lights, and other exterior and interior bulbs.
For the best fit, compare the bulb in your vehicle with the chart before ordering, especially if your 4Runner has been modified or uses an aftermarket lighting setup. Trim and package differences can affect certain positions, and halogen-to-LED conversions may require additional parts, polarity checks, or load resistors to work correctly. If a socket or lens has been changed over the years, the installed bulb may not match the original specification, so it is smart to inspect the bulb already in the vehicle before purchase.
